V8 Javascript engine computes Javascript code into simpler byte code.
Runtime is a stage of the programming lifecycle. Time that a program is running alongside all the external instructions needed for proper execution.
Front and back-end use same language = reuse by modules
Javascript-based = easy entry into server-side programming
SUPER FAST: JIT(Just-in-time) compilation
interpreter = translate program 1 statement at a time
compiler = scans entire program into machine code
Asynchronous I/O
multiple input/outputs at a time
Micro Service Architecture (MSA) compatibility
Read Eval Print Loop
대화형 Shell: fast test without creating file
process by which data/info is converted into electrical/digital signal for transfer
